Abstract

The clutter reduction is one of the most important problems in the ground penetrating radar (GPR) applications. The detection performance of GPR is heavily limited by clutters. In this paper, a novel and simple clutter reduction method based on the design of a symmetry filter, which is adapted to B-scan, is presented. Compared with average subtraction, SaS method and two-dimensional digital filter using the experimental data, the proposed method is more effective on reducing the clutters due to undulated ground bounce, soil roughness scattering and external anomalies reflections.
